It would seem that everything has to be simple – the greater the number, the better the sound. Following this logic, a record 24-bit / 192 kHz should sound better than the 16-bit / 44.1 kHz, right? Unfortunately, it is not so, it’s not so easy is arranged as desired. What is Hi-res Audio?
EVEN BEFORE THE START LISTENING ATTENTION ARE SEVERAL FACTORS.
- What is the quality of the original recording? We are faced with the so-called “high-quality” recordings, which have the characteristics of a 24-bit / 96 kHz or even 24-bit / 192 kHz but are nothing but a cheap recording with the high sampling rate, sold at exorbitant prices. This is a real sell.
- The original, studio recording should have a high quality. If it is poorly mixed by the authors of the track, then no matter how high frequencies, numbers, etc. The good sound recording will not be such.
- Very much depends on the playback equipment that you use. If it produces enough clean sound, there is no chance to hear the difference between hi-res recording and ordinary.
- Impartiality in relation to records is also important.
What is Hi-res Audio? Standard Definition File – 16-bit / 44.1 kHz. This level of music CDs. Anything above it is considered a hi-res recording. What is not always possible to learn about the high-quality (hi-res) record – is that whether it is the quality, which was recorded and compiled in the studio. To clarify this, in some cases, used the term ‘Studio mix “, which means that the record is not compressed.
To make the objective comparison between high quality / recording studio quality and CD quality is sometimes not as easy as you can imagine. I spoke with many people working in and it seems that the quality of the files to a different attitude and different. What is Hi-res Audio? Some studios are more concerned about the high-resolution recordings since they attract the attention of users and will be purchased with more scrupulous attitude to quality. On CD produced usually the hi-res version of a file with a reduced sampling.
Lowering of quality and even causing the loss in sound but, for example, CD-track versions are more suitable for use in advertising or reproducing machine.
And it seemed like once we hi-res version of the track, then technically it will sound better, right? But, again, the answer is not as obvious as it should be.
ABOUT THE DETAILS AND HI-RES: WHAT IS HI-RES AUDIO?
It is best to separate the bit depth (16/24-bit) from the sampling rate (44.1 / 192 kHz) and talk about them separately.
The greater the bit depth, the more accurate the measurement of sound waves, so 24-bit record sounds better than 16-bit. This is because the 16-bit recording is 65.500 degrees measurement sound waves, while the 24-bit recording, the figure is 16 million.

Impressive.
What is Hi-res Audio? What else gives a high bit depth – so it improved the range from the quietest to loudest sound recording: 24 bits provide a range of 144 dB, and 16-bit – 96 dB.
Do not forget that all these data – a theory which shows only the data about the noise generated inside the acoustic equipment. In some cases, you may lose the dynamics of the frequency of 10-20 decibels for technical reasons.
The best classical music recordings have a range of 60 dB, whereas for pop music is an unusual range of more than 15 dB. This means that 16-bit word length is enough to play any genre of music.
Sometimes recording deficiencies can be smoothed using a diluted – adding random noise in the recording. Sometimes the correct noise can improve the overall picture.
WHAT IS THE DIFFERENCE BETWEEN NORMAL RECORDING AND HI-RES?
What is Hi-res Audio? One of the reasons to use a 24-bit – is that during the recording process, there are many events that gradually Bates sound quality.
When the 24-bit recording with a large range has several tracks, then its range is reduced significantly. For example, the recording tracks 48 with a bandwidth could provoke the loss of up to 36 dB.
System noise and other factors such as the need to prevent overloading of the sound can also significantly reduce the dynamic range. Using 24-bit – a small that allows you not to be afraid of these losses and the output is a decent sound.
The reason why the sampling frequency is increased is used, it has a slightly different origin. 44.1KHz not just been selected for CD quality, despite the fact that the maximum that human ears can hear is equal to 20 kHz. By the way, you have to be quite a young man with a sensitive ear to hear the details.
Digital record huge tend to generate unwanted sounds, beyond the limit of the sampling frequency. Such fines should be strictly screened, or they can create sound distortion in the audible range.
This frequency filtering brings a kind of distortion in the audible range. If you raise the sample rate is even higher, these distortions can “move” even higher outside the audible range. Increased frequency also improves the sound highpass some instruments, despite the fact that science says that we can not hear these frequencies.
I once visited one of the branches of the forum, saying that records are of little avail. However, when I got acquainted with some example entries with different frequency, I can not agree with this. Most hi-res files, which I have heard, they sound great.
By comparison, CD-versions of these songs sound like something rude and cropped.
